Can anybody tell me what the taper of an International tie rod end is?
I need to ream some spindles for a "class 9" car.
Need to know what degree of taper ream to get.
Thanx

Depends on the application but it should be 7 degrees total included angle. Stock Car Products sells a reamer for doing that.

Most of the stock car reamers sell for around $100. Snap-On carries a 'repair' reamer for about half of that. You will kill it after about 1/2 dozen holes, but it can be used to ream holes bigger and not just to tune up existing holes.

Yea we tried that once and killed ours in no time at all. As I recall the flutes were straight and it generated a lot of chatter and blew up before we made the first hole. Not really a good reamer for powered machinery. The Stock Car products one has spiral flutes and it's probably done a few hundred holes over the years and is still sharp.

Cameron,
Mine is a 7 degree tapered reamer. I bought it through a machine tool distributor. It cost around $135.00. It has the following markings on it:

Rev 3
RAHCO

For the guy with only a couple holes to modify it does make a pretty good low cost option, but it's far from a production tool.

FWIW I know a guy who runs a cnc grinder. Straight & tapered reams are what he makes all day long. He's offered to make me a ream for the toyota taper. I just need to get him the dims.

I can get a #2 ball joint ream localy for $56.00.
It is 1.5 inches per foot taperWould this be the same as 7 degrees?

As I recall, the angle is not a nice round number but something over 7 degrees. I bought a reamer from SCP around 1989 and am still using it. No one industrial had just the right angle. The angle has to be right or the shank will move in the hole. This will let it come loose and/or cause the threaded section to break off.

alright, 7 degrees is 1.4734 inches per foot, and 1.5 inches per foot is 7.125 degrees.
for future reference, the math used is TAN(angle)=(inches per foot/12)

At baseball games they play organs, in motorsports they donate them.

Its really easy; find out what angle you need, buy the proper straight ream and have it ground to your specs. Its cheap and easy but may take a few days.
